suddenly unable to logon to laptop when remote: "Domain is unavailable".
Posted on 2006-11-27
I am hoping that someone out there has seen this issue before and can help me understand what happened. I have a user with a laptop who often works remotely. She has a non-roaming profile, so when remote, she logs into her computer using her domain credentials and uses the local profile, all as we would expect. This has been working for about a year.
Suddenly today, she was trying to start a program using "run as" for admin rights (as she has done successfully for many months). The system refused the password ("...username or password are incorrect"). I had her log off and try logging on as that user, but it would not do so because "the domain controller cannot be reached". "OK", i think, "maybe I never logged into her computer as that admin user". So I have her try using my admin credentials that I know I have used on her machine before, and it logs in ok. I have her log back in as herself and try to "run as" the account that we just succeeded as logging in as, but it tells her "bad username or password".
Frustrated, I think I will have her log back in under my credentials and make her account a local admin. However, once we log out, we are no longer able to log in as this same admin user; we get "the domain controller cannot be reached.". In fact, we can no longer log in even as her original user! We appear to be completely unable to log into the machine because it cannot find a DC!!
I have never had this problem before and am rather stumped as to what could have caused it? Does anyone out there have any idea
A) why might this happen?
B) how can I get around the problem?
C) how can I prevent it happening again?
I am working on solving number B right now. Currently, I have the user looking for a network cable she can borrow. I am thinking maybe I can have her put a check in "log in using dial-up networking" and connect to the VPN as she logs in. thus allowing her computer to talk to the domain controller. Any thoughts on if this would work?
The user is remote for a series of meetings and not having access to her computer is causing a LOT of stress right now, so any thoughts on solving this are greatly appreciated!
